Dan's Plan

Edit 0 25 …
1. Choosing A Project:

TOPICS THAT INTEREST ME: CURRICULUM CONNECTION:http://www.instructables.com/id/knexmarble-launcher/ im am going to get the idea from this but expand and add my own touch to the final shooter
Force and Motion
What will the distances be when I shoot the gun when i use different rubber bands
INDEPENDENT VARIABLE: Marble Gun

DEPENDENT VARIABLE: Different Rubber bands



2. Investigate the Information:


NOTES/FACTS: I saw that the rubber band is pulled back and shot and there is a pattern with it





NOW THAT I'VE DONE SOME RESEARCH, I PREDICT THE ANSWER TO MY QUESTION WILL BE:That the smaller stronger rubber bands will send the marble further than weak ones that are stretched out.




3. Plan A Procedure:
For my project I will make my gun to the specifications of the website and will shoot it with different rubber bands and calculate the distances






4. What I'll Need:

I have these: I need to locate these:
Knex pieces i can figure how many I will need




5. Keeping Track - Proposed Data Sheet

 Rubberband 1
 Rubberband 2
 Rubberband 3
